With John Heard, Daniel Stern, Kim Greist, Christopher Curry, George
Martin, John Goodman.

1950-ish creature feature has photographer Heard and hippie Stern investigating missing derelicts, recent dismemberments, monster sightings, and toxic waste disposal in the NYC sewers. Hmmm, could they all be linked?

The leads are credible in underwritten roles, and Kim Greist is cute as John Heard's babe who lops off the head of one of the titular mutants with a conveniently located sword (...but not before she has the compulsion to take a relaxing shower when finding a mangled dog in the basement!)
